Choosing Zulip over Slack as our group chat is one
of the best decisions we've ever made. Zulip makes
it easy for our community of 1000 Recursers around
the world to stay involved, even years after their
batches finish. No other tool has a user
experience that scales to a community of our
size.

Zulip’s unique threading saves me well
over an hour a day in working with our
distributed team of engineers and PMs
across 7+ time zones. We tried Slack,
Mattermost, and other team chat
products that claim to support
threading, and nothing handles
synchronous and asynchronous
communication so intuitively.
